One оf the mаjоr prоblems with Unicode is thаt it cаnnot represent symbols other than those found in the English language.
Fоr this prоblem, yоu will be writing а clаss nаmed MyArrayQueue that provides an implementation of the interface below. Make sure that you are not using any raw types (i.e. you must use the generic type parameter in your solution). You do not need to include any import statements in your response. And, of course, assume the interface below compiles. public interface QueueInterface extends Iterable { int size(); void clear(); void insert(T data, int index) throws IndexOutOfBoundsException, IllegalArgumentException; void enqueue(T data) throws IllegalArgumentException; T remove(int index) throws IndexOutOfBoundsException; T dequeue();} It's recommended that you read ALL of the following requirements before implementing (there are HINTS). It's strongly recommended that you implement the methods in the order in which they are detailed below to maximize code reuse and make the best use of your time. The MyArrayQueue class must have a private array of type T to store the elements. This class must also have a single, no-argument constructor that creates the generic array of type T with initial length of 10. NOTE: For ease of implementation, you can assume that new T[length] is valid syntax for creating a new array of type T. You can earn 5 bonus points if you know the correct way to create a new array of type T that will compile in Java. The MyArrayQueue class should also have a nested inner class named MyArrayQueueIterator that satisfies the requirements of the Iterator interface. Remember that nested inner classes have access to the private data members of the enclosing class (i.e. the iterator will be able to access the backing array and any other fields the queue class has)! Think carefully about what state information an iterator over an array will need and don't overcomplicate it. Don't forget that one of the Iterator methods should throw a NoSuchElementException when the iterator is asked to return an element that doesn't exist! The message should tell the user that the queue is empty. Also recall that a queue is a FIFO structure, meaning that the first element enqueued onto the queue will be the first element dequeued from the queue. Descriptions of the behaviors for the QueueInterface methods are detailed below. int size() returns number of elements currently in the queue HINT: the size of the queue isn't the same as the length of the backing array. You'll want to keep track of the logical size of the collection using a private field. void clear() Empties the queue of all elements. The size of the queue should be zero after this method is called void insert(T data, int index) throws IndexOutOfBoundsException, IllegalArgumentException Inserts an element at the specified position in the queue, where index 0 represents the first element to be removed (i.e. dequeued). Remaining elements should be moved "downwards" (see diagram). If the underlying array is full when an element is inserted into the queue at a valid index, it should be increased in size using the following method which you can assume exists: ArrayQueueUtils.doubleLength(T[] arr); // returns a T[] that is a deep copy of the T[] arr that is passed in. The returned array will have double the length of the array passed in. throws IndexOutOfBoundsException when the index is invalid. The message should contain text describing the reason the index is invalid. An index is invalid if: the value of the index is negative the value of the index exceeds the size of the queue. NOTE: an index that points to the next immediately available slot is VALID (i.e. inserting at an index equal to the size is a valid operation) You may assume that IndexOutOfBoundsException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. throws an IllegalArgumentException when the reference passed in for the data is null. The message should contain text describing the reason the argument is illegal. You may assume that IllegalArgumentException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. HINT: it's strongly recommended this method is implemented before enqueue void enqueue(T data) throws IllegalArgumentException The element that was placed (i.e. enqueued) onto the queue will be the last element removed (i.e. dequeued) from the queue and the existing elements will maintain their current positions (see diagram). If the underlying array is full when an element is enqueued onto the queue, it should be increased in size using the following method which you can assume exists: ArrayQueueUtils.doubleLength(T[] arr); // returns a T[] that is a deep copy of the T[] arr that is passed in. The returned array will have double the length of the array passed in. throws an IllegalArgumentException when the reference passed in for the data is null. The message should contain text describing the reason the argument is illegal. You may assume that IllegalArgumentException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. HINT: using the insert method to implement enqueue makes this method VERY short! T remove(int index) Removes and returns an element at the specified position in the queue, where index 0 represents the first element to be removed (i.e. dequeued). Remaining elements should be moved "upwards" (see diagram). throws IndexOutOfBoundsException when the index is invalid. The message should contain text describing the reason the index is invalid. An index is invalid if: the value of the index is negative the value of the index does not point to an element that exists within the queue. NOTE: an index that points to the last element is VALID You may assume that IndexOutOfBoundsException is an unchecked exception and has a constructor that takes in a single String parameter representing the message. HINT: it's strongly recommended this method is implemented before dequeue T dequeue() The first element that was placed (i.e. enqueued) onto the queue will be the first element removed (i.e. dequeued) from the queue and the existing elements will be moved "up" (see diagram). returns null if queue is empty HINT: using the remove method to implement dequeue makes this method VERY short! IMPORTANT: DON'T FORGET TO IMPLEMENT THE METHOD(S) REQUIRED BY THE Iterable INTERFACE! Make sure to select the 'Preformatted' style from the dropdown so your code is formatted clearly. DO NOT USE THE TAB KEY WHEN WRITING CODE AS YOU MAY ACCIDENTALLY SUBMIT YOUR EXAM. USE THE SPACE BAR INSTEAD. Tentative estimated breakdown of the points for this question is as follows: ITEM POINTS size & clear methods 10% insert & enqueue methods 30% remove & dequeue methods 30% MyArrayQueue class (misc.) 10% MyArrayQueueIterator class (misc.) 20%
